Drivers for installing Windows 98SE or Windows ME on an IBM Thinkpad T42 laptop

NOTE:

All the drivers posted here were located through extensive google searching, Lenovo does not support Windows 98SE or Windows Me on this laptop model.

DISCLAIMER:

I have only tested Windows Me at this point in time, however, the drivers and instructions posted here should be compatible Windows 98SE. If you encounter missing CD drivers when installing 98SE, you'll have to devise a way to get the motherboard driver into the hard drive so 98SE can install it and get the CD drive working, be it editing the hard drive externally or installing an inappropriate CD driver. The rest of the drivers should work fine. I may later update this thread with 98SE instuctions too.

Most of the drivers make no mention of Windows 95 or Windows 98SE, I have no idea if those will work.

Also, IBM did offer the Thinkpad T42 with a few different customizations. In the future I may revise the driver download here to include any other devices that the Thinkpad T42 is known to ship with. In regards to the Radeon chipset, the WME 8.03 Catalyst driver should include support for the Radeon 9000 and Thinkpad T42 video chipsets.

INSTRUCTIONS:

Included with the .zip file. I left the names of the drivers unedited so they are more recognizable.

Everything included should install without a hitch, except the ATi Radeon 7500 driver. You will have to manually install the display driver. If using Windows Me, you'll have to force it to accept the driver as it doesn't have a digital certificate from Microsoft. The wireless systray program had trouble running after reboot, using Windows Me. Using KernelEx 4.5 Final to run the systray program in 98SE mode seemed to help. The wireless settings are found in the configuration tab.

Out of all the drivers, the ATi Catalyst driver for the Radeon 7500 was by far the hardest to find. I must have gone through a dozen drivers before I found one that finally worked without Windows ME booting to a black screen instead of the desktop.

IBM Thinkpad T42
Windows 9x Instructions:

Intel 855PM:
Run either 'infinst_autol.exe' or 'infinst_enu.exe'. 

ATi Radeon 7500: 
Unpack WME 8.03 catalyst driver. To install display driver, open display properties in device manager, update driver, specify location, select driver from list, have disk, go to 9x INF folder in the unpacked WME 8.03 installer and finally pick either of the three RADEON 7500 SERIES entries from the giant driver list (scroll way down). If using Windows ME, you have to allow the uncertified driver to install, pick advanced option when offered and turn off the auto rejection. Install ATI Control Panel from the unpacked installer to finish. 

SoundMAX:
Run either 'd64z32us.exe' or 'sp24465.exe'. 

Intel PRO/10/100/1000 LAN Adapter:
Run 'tpet1u98.exe'.

Atheros/intel/thinkpad wireless

Thinkpad T42
Windows 9x Instructions: 
Run '1qwc70ww.exe'. When installing the wireless driver (assuming you have the atheros/intel type wireless card), the driver and client should install fine. A possible issue may crop up when you restart Windows and the systray icon is supposed to appear. Sometimes it crashes, not sure why. When using Windows ME OEM, I tried installing KernelEx 4.5 Final and set the systray icon for the wireless client to Windows 98SE compatibility. That seemingly stopped the crashing. Windows 98SE may not require this. Just jotting this down just in case. 
The installer 'tpet1u98.exe' is there just in case the installer mentioned above doesn't work for you. 

TI Cardbus Controller:
Run 'ossa04ww.exe'

Drivers not included:
Modem
SMBus
